BlackRock’s iShares Bitcoin Trust (IBIT) has surpassed 700,000 Bitcoin in holdings, marking a significant milestone for the spot Bitcoin exchange-traded fund.

The asset milestone was reached following a $164.6 million net inflow into the fund on Monday.
Outpaces other Bitcoin ETFs and corporate treasuries
Since launching in January 2024, IBIT has become the dominant US spot Bitcoin ETF.
It now accounts for over 55% of total BTC held across all US spot Bitcoin ETFs, according to data from Bitbo.
Its 18-month growth trajectory places it ahead of other leading funds in the category, including Fidelity’s FBTC, which holds around 203,000 BTC, and Grayscale’s GBTC, which holds approximately 184,000 BTC.
The ETF has also eclipsed the holdings of Michael Saylor’s Strategy (MSTR), which began accumulating Bitcoin in 2020 and currently holds around 600,000 BTC.
Strategy is the largest corporate holder of Bitcoin to date.
Since its inception, IBIT has delivered a total return of 82.67%, according to fund performance data tracked by market analysts.
Revenue surpassing flagship S&P 500 ETF
BlackRock’s Bitcoin ETF is now one of the firm’s top-performing products.
IBIT has become the third-highest revenue-generating ETF across BlackRock’s portfolio, which comprises over 1,100 funds.
It now reportedly generates more revenue for the asset manager than the iShares Core S&P 500 ETF (IVV), BlackRock’s flagship fund tracking the US equity benchmark, and the iShares Russell 2000 ETF (IWM), which tracks small-cap US stocks.
“New milestone, iShares Bitcoin ETF now holds over 700,000 BTC. 700,000. Did this in 18 months. Ridiculous,” Nate Geraci, president of The ETF Store, wrote on X.
Senior Bloomberg ETF analyst Eric Balchunas also noted the significance of IBIT’s rise in BlackRock’s rankings, underscoring its rapid emergence as a cornerstone product in the firm’s ETF offerings.
IBIT’s rapid growth coincides with strong demand for spot Bitcoin ETFs in the US market, which collectively have attracted over $50 billion in net inflows since launching in January 2024.
These ETFs are considered the most successful ETF introductions in US financial history.
According to research from Galaxy Digital, the combined buying activity of US Bitcoin ETFs and Strategy has consistently outpaced Bitcoin’s net new issuance from miners.
In 2025 alone, these entities have purchased $28.22 billion worth of Bitcoin, compared to $7.85 billion in new Bitcoin generated by miners.
Galaxy noted that this demand-supply imbalance has persisted every month except February, when the group recorded net Bitcoin sales totaling $842 million.
